When implementing a parallel structure, why does MATLAB serial read produce an error?

edit

MATLAB serial read operates in a serial manner, meaning it reads data from the serial port one byte at a time. When implementing a parallel structure, multiple processes are running in parallel and attempting to access the serial port simultaneously, which can cause conflicts and errors. Additionally, parallel processing may cause issues with data timing and synchronization. Therefore, using MATLAB serial read in a parallel structure is not recommended and can lead to errors. Instead, other communication methods such as TCP/IP or messaging systems should be used to facilitate communication between the parallel processes.
